IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 176,259, dated April18, 1876; application filed January 27, 1876.

To all whom it may concern Be it known that I, HENRY KALEB AN- DREWS, ofDecatur, in the county of Wise and State of Texas, have invented certainnew and useful Improvements in Horse Powers, of which the following is aspecification:

My invention consists. in constructing a horse-power with amaster-wheel, communieating, through a pinion, crank, andpitman, with anoscillating weighted tappet, adapted to communicate a rotation to aduplex ratchetwheel, as hereinafter described.

In the accompanying drawing, Figure 1 is a plan or top view of myimproved horsepower. Fig. 2 is a front elevation of the same. Fig. 3 isa perspective view of the oscillating tappet, and a portion of theduplex ratchetwheel on which it operates.

A represents a stationary frame, supporting a vertical shaft, B, whichis provided with a sweep, S, for the attachment of the team, and carriesat its upper end a master-whee], O, beveled in customary manner, anddriving a beveled pinion, d, which is keyed -to a shaft, D, carrying atthe outer end a crank-wheel, E, to the wrist c of which is applied apitman, F, which is pivoted at its other end to a box, G, sliding insegment-guides H. The box G is formed with horizontal lugs or gudgeonsg, to work in the guides H, with an aperture to receive a pin, 1,projecting upward from the top of a tappet, J, to which is attached aweight, K. L L are a pair of ratchetwheels, with their teeth I lalternately arranged-that is to say, with the teeth of one wheelopposite the intervals between the teeth of the other wheel. The tappetJ is formed with teeth j j, adapted to engage with the teeth I l of thewheels L and L.

Operation: From the above description it will be understood that whenthe master-wheel O is rotated by the team, the motion will becommunicated, through the pinion-shaft D, crankwheel E, and pitman F, tothe upper end of the tappet J, so as to impart an oscillating motionthereto. Its alternate sides are drawn up over the teeth I l of thewheels L L, and the tooth j, as it reaches the' uppermost position,engages with a tooth on the wheel L, while the other tooth, j, riseswith the reverse motion of the tappet, so as to climb on the teeth I,and vice versa. The effect of this motion is to cause the weight K toact constantly on the double ratchet-wheel L L, and impart a continuousrotation thereto, the motion being communicated by a band, pulley, orcrank, in any customary manner, to any machinery which it is desired todrive.

Having thus described my invention, What I claim as new, and desire tosecure by Let ters Patent, is

A horse-power constructed, substantially as herein set forth, with atappet oscillated by the power of the team, and weighted, so as tocommunicate rotation to a driving-wheel, as

explained.
